Organic insecticides

Their most valuable quality is the fact that they are not dangerous for humans, plants, soil, generally for environment. They can be obtained from substances near at hand and without exorbitant prices.

They can be used on infested plants or as preventive method.

Because the insects react to odors, vapours, gases, fumes, heat, oils, soap etc., all these are used as/in organic insecticides. For example, the strong smell of garlic, tobacco, rhubarb and other plants are repellent for some insects. The hot peppers, alcohol, salt and other substances can burn and kill the pests. The oils suffocate some insects, the soap and the detergents added to solutions make the ingredients to stick on leaves and stalks. You can use organic soaps and detergents.

Don't use insecticides on sunny, hot weather because this will burn the plants and it's better if you sprinkle just a single plant at first to see if unwanted effects appear. The best time to apply insecticides is the morning and the evening.

Don't use insecticides if you can pick the pests by hand. Also keep in mind that not only the pest insects can be killed but the beneficial insects too. The plants have the capacity to protect themselves against some pests and growing companion plants is a good way for pest control. So you don't have to use insecticides every day but only when it is necessary.
